During a plumbing inspection, what might indicate a leak?

In the context of a plumbing inspection, observing puddles of water or staining on walls is a strong indication of a potential leak. Such visual signs typically suggest that water is escaping from pipes, fixtures, or appliances and coming into contact with surfaces where it can accumulate or leave marks. Stains on walls can also indicate the path water has taken as it travels, which can help pinpoint the source of the leak. Inspectors are trained to look for these indicators as they can provide immediate insight into plumbing issues that need to be addressed.

In contrast, high-pressure water flow does not indicate a leak; rather, it suggests that water is moving through the system effectively. While this is essential for proper function, it doesn’t provide clues about leaks. The use of cleansing agents is unrelated to leak detection; it's more about maintenance. Lastly, the color of pipes alone does not signify leakage. While material and color can have implications for the overall plumbing system, they do not directly indicate whether a leak is present.
